Palm Sign
Camera → pattern → signature

A signature inspired by the geometry of your palm.

Palm Sign turns live hand landmarks into a refined, personal digital graphic — without saving raw camera video, frames, or palm photographs.

Demo Mode

Simulated Palm Pattern

Camera or model initialization was unavailable. The preview uses synthetic landmark geometry and is clearly marked as simulated.

Palm crease extraction

Demo Mode — Simulated Palm Pattern

This extracts visible crease-like structures from the current camera frame inside the detected palm region. Hand landmarks define the region only; they are not drawn as the signature. The original camera frame is not saved.

Extract a palm pattern to generate your signature

Experimental palm-pattern-generated digital graphic. This is not biometric authentication, identity verification, or a guarantee of uniqueness or legal validity.

Waiting for a detected handTip: keep your hand steady for a cleaner result.

Important: Palm Sign creates an experimental palm-pattern-generated digital graphic. It does not read detailed palmprints, establish identity, provide biometric authentication, prove legal validity, or guarantee uniqueness. Whether a generated graphic is accepted depends on the organization, workflow, or document where it is used.

Camera stays on your device

Palm Sign uses MediaDevices for the live camera and MediaPipe Hand Landmarker for on-device hand landmarks. Raw video, frames, and palm photographs are not saved by the app. Only generated signature history is kept in browser LocalStorage.

MediaPipe processing is local; its library may send usage metrics as described by Google.
